Not a scientist in this field at all but could it possibly have less interference from mediums such as the atmosphere? Hence less signal loss over transmission

- pizza 8y agoimo it seems like data transfer would be difficult to use gravitational waves for. LIGO had to measure very tiny compressions occurring due to very very big things happening faraway in the universe (though I guess being distant isn't a prereq): > On January 4th, 2017, LIGO detected two black holes merging into one. One of the black holes was 32 times the mass of the Sun (32 M⊙, where M denotes mass and ⊙ is a symbol for the Sun) while the other was 19 times the mass of the Sun. When they merged, they created a black hole 49 times the mass of the Sun. The coalescence instantly converted 2 solar masses of black hole mass into the energy that rattled spacetime enough to generate the gravitational waves we detected almost 3 billion years after it occurred. (Caltech/MIT/LIGO Lab) > Despite the stupendous energy released by colliding black holes, detecting gravitational waves is excessively difficult since the effects they have on LIGO’s instruments are incomprehensibly small. This latest wave caused the spacetime occupied by LIGO’s arms to stretch and shrink by 0.000,000,000,000,000,001 (or 1×10-18) meters (a.k.a. an “attometer”). That’s 1000 times smaller than a proton!

- ThePhysicist 8y agoIt surely is science fiction today but from a physics point of view there's nothing that would make it impossible. So as a physicist I'd say it's merely an engineering problem ;)
